Sering kali, kami mendengar pertanyaan, "Apakah Anda memiliki semacam panduan yang menjabarkan proses migrasi dari instalasi lokal ke Bird"?
Mengapa ya, ya memang benar. Teruslah membaca.
First, some back story. The Bird Cloud service was created in 2014 out of the enormous success of the On-Premises Momentum MTA solution. Momentum sits at the core of the Bird Cloud, providing high-speed delivery and traffic shaping for thousands of customers on the cloud service. Because of this, Momentum receives a large portion of our engineering attention, but the results of that work are often buried in performance improvements that don’t get a great deal of press. Momentum customers see the benefits of this work every time a new public release of Momentum is published.
This does NOT mean that Bird is just “Momentum in the Cloud”. MessageBird is much more than that and can have added benefits for customers who choose to migrate or use them in a hybrid approach. In addition, we have made it very easy for PowerMTA customers to migrate or use PowerMTA with Bird in a hybrid configuration as well. The rest of this document will describe in detail how you can migrate your message streams from Momentum or PowerMTA to the Bird Cloud service.
Tdi sini are really two separate scenarios to consider when migrating to Bird from Momentum or PowerMTA.
You are ready to leave the on-premises world entirely, shut down your physical data centers and no longer manage any on-premises MTA directly. This means eliminating Momentum or PowerMTA from your deployment and sending messages directly to SparkPost for message handling. Or
You have reason to keep some on-premises footprint for one reason or another. Some possibilities might be:
aliran pengiriman tertentu yang memerlukan pra-pemrosesan di Momentum
pemisahan kapasitas untuk kebutuhan ledakan atau pemulihan bencana
mendukung pelanggan lama di PMTA sambil mengalihkan pelanggan baru ke SparkPost
…then you want to forward the other messages on to Bird for onward message handling.
In either situation, you need to be aware that Bird will only accept SMTP messages for delivery that are injected over port 587 or 2525 and use SMTP_Auth with a specific username and password (Lihat dokumen SMTP di sini). We also highly recommend connecting with a TLS connection, but that is not strictly required. If you are replacing your MTA layer entirely (scenario 1), then you may also want to consider using the Transmissions REST API which can accept messages over HTTPS connections. Dokumentasi on that API is di sini.
Opsi mana yang saya pilih?
Untuk mengetahui apakah Anda termasuk dalam opsi #1 atau opsi #2, pertimbangkan faktor-faktor ini:
Apakah Anda menggunakan mesin skrip Lua dari Momentumuntuk sesuatu yang lebih rumit daripada perutean pesan?
Lua is a comprehensive script tool for manipulating messages in-line, but the vast majority of our users only use it to select a binding for delivery. If that is the case, you can modify your generation code to add an atribut ip_pool to the X-MSYS-API header and have Bird assign the route for you.
Jika Anda menggunakan Lua untuk melakukan hal-hal yang lebih rumit seperti pemfilteran tubuh, penulisan ulang Mail_From, atau perhitungan irama pesan, dan tidak memungkinkan untuk memindahkan logika tersebut ke dalam aplikasi penyuntikan Anda, Anda dapat mempertimbangkan untuk beralih ke Opsi # 2.
Apakah sistem generasi Anda dapat mengirim pesan melalui port 587 menggunakan TLS dan SMTP_Auth?
Beberapa sistem manajemen kampanye hanya dapat mendorong email keluar pada port 25 dalam bentuk cleartext. Hal ini menyebabkan masalah keamanan untuk Bird sehingga Anda mungkin ingin mempertimbangkan Opsi #2
Apakah Anda menggunakan sintaks substitusi PowerMTA atau modifikasi pesan in-line lainnya?
If you can move this function up into your generators or use the Bird Bahasa Templat, then you can still use option 1, but otherwise, you may need to think about keeping a PMTA node online for this message modification before shipping to Bird for delivery.
Do you require any inbound AV/AS scanning before injection? While this is possible in Momentum and PowerMTA, eBird assumes you have already performed all those checks. You may want to consider doing that before injection.
No matter which way you go, it is sure to affect your commercial relationship. As you can imagine, this is not our first rodeo. Be sure to loop in your Commercial Account Manager and Customer Success Manager so we can help you through the details and make sure you are getting the best value for your dollar.
Untuk Opsi #1 Camp (Melakukan "kalkun dingin"):
Let’s assume you are OK with option 1 and you are ready to shut down your on-premises MTAs and you have decided to continue using the SMTP injection method, not changing your message creation systems at all. Your generation systems should create a fully formatted SMTP message, then push to Bird over TLS using SMTP_AUTH wdi sini the username and password are as described on halaman ini. Remember that the “password” is the API key you generate in your Bird account with the SMTP delivery option turned on.
If you are in the Option #1 camp, consider switching to the REST API right out of your generation system. In most cases, we find that customers’ processing systems are already using JSON over HTTP and have to convert to SMTP before injection. You can skip that step and send it directly to us as muatan REST berformat JSON.
If you choose to inject with the REST API, you may need to alter your content creation system a bit, but it may be worth it. Anda dapat mengetahui lebih lanjut di sini.
One of the biggest concerns large ESPs have with a Migration is IP Warming. Typically they have spent many years grooming their inventory of IP addresses with great care so the thought of abandoning all that work is painful. Bird has worked out a Bring Your Own IP (BYOIP) process that takes care of that issue. If you have at least one contiguous /24 CIDR block, Bird can use those existing IPs for delivery which saves you the pain of having to warm them up again. If you are able to take advantage of that option, you can skip the section di sini on IP warmup.

Opsi Leveraging #2 (pra-pemrosesan di muka):
Namun, jika Anda berada di tim Opsi # 2, maka Anda akan ingin menambahkan beberapa perubahan konfigurasi pada penerapan Anda. Cara yang paling tidak menyakitkan untuk memigrasikan beberapa aliran pesan tertentu dari Momentum atau PMTA ke Bird sambil tetap menggunakan injeksi SMTP dari sistem pembuatan Anda adalah dengan menambahkan rute khusus dalam konfigurasi Anda.
Untuk Momentum:
Set up a version of Momentum > 3.6.23.
Install a valid SSL Certificate and open outbound port 587 so Momentum can talk to Bird Configure an outbound domain so you can route a message through Momentum to Bird.
With the configuration below, any message hitting this configuration will be routed to smtp.sparkpostmail.com using port 587 and SMTP_Auth with the username and password defined tdi sini.outbound_smtp_auth { } Keep_Message_Dicts_In_Memory = true Domain "smtp.sparkpostmail.com" { Remote_SMTP_Port = "587" Outbound_SMTP_AUTH_Type = "LOGIN" Outbound_SMTP_AUTH_user = "SMTP_Injection" Outbound_SMTP_AUTH_pass = "17258redacted8bd6cd7a8redacted8c22bce" }
Configure the bindings you want to relay through MessageBird with TLS and gateway them to the domain you defined above.
Catatan: TLS is not strictly required but is a strong recommendation. If TLS is not possible for some reason, then IP whitelisting the API keys is also a strong recommendation.binding “CustomerA-Outbound” { Gateway = "smtp-demo.sparkpostelite.com" TLS = "required" TLS_Certificate = "/etc/pki/tls/certs/trymsys.net.crt" TLS_Key = "/etc/pki/tls/certs/trymsys.net.key" TLS_Ciphers = "DEFAULT" }
Untuk PowerMTA:
Set up a version of PowerMTA > 4.5.0
Instal Sertifikat SSL yang valid dan buka port keluar 587 sehingga PowerMTA dapat berbicara dengan Bird.
Configure an outbound domain path so you can route a message through PowerMTA to Bird. With the configuration below, any message hitting this configuration will be routed to smtp.sparkpostmail.com using port 587 and SMTP_Auth with the username and password defined tdi sini. In PowerMTA, this is also wdi sini you can set TLS. Perhatikan bahwa hal ini juga didokumentasikan lebih lengkap di sini
<domain sparkpost.rollup> use-unencrypted-plain-auth yes auth-username SMTP_Injection auth-password YourAPIKeygoesdi siniwhenyougenerateit route smtp.sparkpostmail.com:587 use-starttls yes require-starttls yes max-smtp-out 10 </domain>
4. Konfigurasikan VMTA yang ingin Anda relai melalui Bird dengan konfigurasi rollup {sparkpost} yang telah Anda tetapkan di atas.
<virtual-mta SparkPostRelay> <domain *> queue-to {sparkpost} </domain> </virtual-mta>
Once you have those configuration changes made, any messages sent to the selected “binding” or “VMTA” should be routed automatically through Bird for delivery.
Mewujudkannya
When you start down this road, don’t make the mistake of thinking this is an overnight operation. Doing this right will take some time and care.
Setup your Bird account and fully test using a development subrekening so you can filter out that traffic later. You will need to do this for either option because you will need the API key for the SMTP_Auth password either way.
If you are using SMTP injection, plan to add an X-MSYS-API header to incorporate all the metadata and message attributes needed. Any X-Headers should be re-written as metadata and you should include the ip_pool and campaign attributes as well. A sample is available di sini
If you are NOT using BYOIP, then you should make sure you set up slightly different sending domains for use with MessageBird so that you can run both environments in parallel for as long as it is needed. If your current sending domain is mycompany.com, maybe set up sp.mycompany.com specifically for Bird delivery. This allows you to migrate slowly and carefully while not compromising either domain.
Make sure you have full domain alignment and security features enabled. In DNS, set up DKIM, SPF, DMARC, bounce and tracking domains so they all look like they belong to the same organization.
Configure Pemanasan IP Otomatis on your defined IP_Pools. If you are using the previously mentioned BYOIP option, you can ignore the warmup step.
Start with one message stream and move forward from there. Just like IP Warmup, you don’t want to do this all at once. Redirect a few hundred messages first, then 10% of the volume, then 20% the following day and increase until you have moved all the volume over. If you are an ESP, select a customer you can work with and test the process with their feedback. If it all works well, move on to the next one. If you run into problems, take the time to fix it and work it into the process for the next one.
Automate as much as possible with Api. Outside of the DNS changes, the SparkPost config can be mostly automated with beberapa panggilan API.
Pengumpulan Data dari Bird
MessageBird reports message delivery in a webhooks feed or in the message events API. Accessing Bird plain text logs is just not possible. You can pull this data back to your environment with a webhooks collector or by calling the API Peristiwa periodically and consuming the data. We recommend using webhooks and have beberapa rekomendasi on doing that right. In its most basic form, a PHP webhook collector can be deployed in a few lines of code:
<?php $verb = $_SERVER['REQUEST_METHOD']; if ($verb == "POST") { $jsonStr = file_get_contents("php://input"); http_response_code(200); $rnum = rand(1000,9999); $t = date("YmdHis") . $rnum; $Jfile = './data/data_'.$t.'.txt'; if (file_exists($Jfile)) { $fn = basename($Jfile,".txt"); $seq = 0; $ftail = substr($fn,-2,1); if ($ftail == "-"){ $seq = substr($fn,-1); } $seq++; $Jfile = basename($Jfile,".txt")."-".$seq.".txt"; } $fh = fopen($Jfile, "w") or die("Unable to create file!"); fwrite($fh, $jsonStr); fclose($fh); } ?>
While you are experimenting, you can try them out with free collectors such as http://webhook.site/.
Once you have collected all the webhook data, you can read that into a data store for additional processing. There are also ways to push Webhooks through services like StitchData and Segment.
The same information is available in the API Peristiwa if you have a need to PULL the data and cannot accept PUSH data. Here is a sample Event API call:
GET https://api.sparkpost.com/api/v1/events/message?/
recipients=recipient@example.com&templates=my-template&events
That API is fully documented with samples here: https://developers.sparkpost.com/api/events/#events-get-search-for-message-events
If you really need the event data back in a form that looks like PMTA or Momentum logging, that is possible as well if you employ some additional conditioning code. The great news is there are beberapa contoh to steal from already.

Make sure you talk to your Sales and Success Management team. We’ve done this before and can help you through it quickly and cost-effectively.
Figure out if you are in Camp #1 (dapat berpindah sepenuhnya dari On-Prem) or Camp #2 (Masih membutuhkan beberapa MTA on-prem).
Sign up for a akun tes gratis to evaluate the integration details.
Jika Anda menggunakan injeksi SMTP, cari tahu cara memasukkan data header dan atribut pesan ke dalam header X-MSYS-API.
Confirm if you can use our BYOIP process.
Perbarui DNS Anda dengan domain baru jika perlu.
Build a small sample to test your migration. You may need to adjust your config.
Tingkatkan volume hingga semua lalu lintas dimigrasikan
Jika Anda masuk ke dalam Camp #1, Anda akhirnya bisa mematikan MTA on-prem Anda setelah semua trafik dimigrasikan.

Install a valid SSL Certificate and open outbound port 587 so Momentum can talk to Bird Configure an outbound domain so you can route a message through Momentum to Bird.
With the configuration below, any message hitting this configuration will be routed to smtp.sparkpostmail.com using port 587 and SMTP_Auth with the username and password defined there.outbound_smtp_auth { } Keep_Message_Dicts_In_Memory = true Domain "smtp.sparkpostmail.com" { Remote_SMTP_Port = "587" Outbound_SMTP_AUTH_Type = "LOGIN" Outbound_SMTP_AUTH_user = "SMTP_Injection" Outbound_SMTP_AUTH_pass = "17258redacted8bd6cd7a8redacted8c22bce" }
Configure the bindings you want to relay through MessageBird with TLS and gateway them to the domain you defined above.
Catatan: TLS is not strictly required but is a strong recommendation. If TLS is not possible for some reason, then IP whitelisting the API keys is also a strong recommendation.binding “CustomerA-Outbound” { Gateway = "smtp-demo.sparkpostelite.com" TLS = "required" TLS_Certificate = "/etc/pki/tls/certs/trymsys.net.crt" TLS_Key = "/etc/pki/tls/certs/trymsys.net.key" TLS_Ciphers = "DEFAULT" }
Untuk PowerMTA:
Set up a version of PowerMTA > 4.5.0
Instal Sertifikat SSL yang valid dan buka port keluar 587 sehingga PowerMTA dapat berbicara dengan Bird.
Configure an outbound domain path so you can route a message through PowerMTA to Bird. With the configuration below, any message hitting this configuration will be routed to smtp.sparkpostmail.com using port 587 and SMTP_Auth with the username and password defined there. In PowerMTA, this is also where you can set TLS. Perhatikan bahwa hal ini juga didokumentasikan lebih lengkap here
<domain sparkpost.rollup> use-unencrypted-plain-auth yes auth-username SMTP_Injection auth-password YourAPIKeygoesherewhenyougenerateit route smtp.sparkpostmail.com:587 use-starttls yes require-starttls yes max-smtp-out 10 </domain>
4. Konfigurasikan VMTA yang ingin Anda relai melalui Bird dengan konfigurasi rollup {sparkpost} yang telah Anda tetapkan di atas.
<virtual-mta SparkPostRelay> <domain *> queue-to {sparkpost} </domain> </virtual-mta>
Once you have those configuration changes made, any messages sent to the selected “binding” or “VMTA” should be routed automatically through Bird for delivery.

When you start down this road, don’t make the mistake of thinking this is an overnight operation. Doing this right will take some time and care.
Setup your Bird account and fully test using a development subaccount so you can filter out that traffic later. You will need to do this for either option because you will need the API key for the SMTP_Auth password either way.
If you are using SMTP injection, plan to add an X-MSYS-API header to incorporate all the metadata and message attributes needed. Any X-Headers should be re-written as metadata and you should include the ip_pool and campaign attributes as well. A sample is available here
If you are NOT using BYOIP, then you should make sure you set up slightly different sending domains for use with MessageBird so that you can run both environments in parallel for as long as it is needed. If your current sending domain is mycompany.com, maybe set up sp.mycompany.com specifically for Bird delivery. This allows you to migrate slowly and carefully while not compromising either domain.
Make sure you have full domain alignment and security features enabled. In DNS, set up DKIM, SPF, DMARC, bounce and tracking domains so they all look like they belong to the same organization.
Configure Pemanasan IP Otomatis on your defined IP_Pools. If you are using the previously mentioned BYOIP option, you can ignore the warmup step.
Start with one message stream and move forward from there. Just like IP Warmup, you don’t want to do this all at once. Redirect a few hundred messages first, then 10% of the volume, then 20% the following day and increase until you have moved all the volume over. If you are an ESP, select a customer you can work with and test the process with their feedback. If it all works well, move on to the next one. If you run into problems, take the time to fix it and work it into the process for the next one.
Automate as much as possible with APIs. Outside of the DNS changes, the SparkPost config can be mostly automated with beberapa panggilan API.
Pengumpulan Data dari Bird
MessageBird reports message delivery in a webhooks feed or in the message events API. Accessing Bird plain text logs is just not possible. You can pull this data back to your environment with a webhooks collector or by calling the Events API periodically and consuming the data. We recommend using webhooks and have beberapa rekomendasi on doing that right. In its most basic form, a PHP webhook collector can be deployed in a few lines of code:
<?php $verb = $_SERVER['REQUEST_METHOD']; if ($verb == "POST") { $jsonStr = file_get_contents("php://input"); http_response_code(200); $rnum = rand(1000,9999); $t = date("YmdHis") . $rnum; $Jfile = './data/data_'.$t.'.txt'; if (file_exists($Jfile)) { $fn = basename($Jfile,".txt"); $seq = 0; $ftail = substr($fn,-2,1); if ($ftail == "-"){ $seq = substr($fn,-1); } $seq++; $Jfile = basename($Jfile,".txt")."-".$seq.".txt"; } $fh = fopen($Jfile, "w") or die("Unable to create file!"); fwrite($fh, $jsonStr); fclose($fh); } ?>
While you are experimenting, you can try them out with free collectors such as http://webhook.site/.
Once you have collected all the webhook data, you can read that into a data store for additional processing. There are also ways to push Webhooks through services like StitchData and Segment.
The same information is available in the Events API if you have a need to PULL the data and cannot accept PUSH data. Here is a sample Event API call:
GET https://api.sparkpost.com/api/v1/events/message?/
recipients=recipient@example.com&templates=my-template&events
That API is fully documented with samples here: https://developers.sparkpost.com/api/events/#events-get-search-for-message-events
If you really need the event data back in a form that looks like PMTA or Momentum logging, that is possible as well if you employ some additional conditioning code. The great news is there are beberapa contoh to steal from already.
Rekap
Make sure you talk to your Sales and Success Management team. We’ve done this before and can help you through it quickly and cost-effectively.
Figure out if you are in Camp #1 (dapat berpindah sepenuhnya dari On-Prem) or Camp #2 (Masih membutuhkan beberapa MTA on-prem).
Sign up for a akun tes gratis to evaluate the integration details.
Jika Anda menggunakan injeksi SMTP, cari tahu cara memasukkan data header dan atribut pesan ke dalam header X-MSYS-API.
Confirm if you can use our BYOIP process.
Perbarui DNS Anda dengan domain baru jika perlu.
Build a small sample to test your migration. You may need to adjust your config.
Tingkatkan volume hingga semua lalu lintas dimigrasikan
Jika Anda masuk ke dalam Camp #1, Anda akhirnya bisa mematikan MTA on-prem Anda setelah semua trafik dimigrasikan.
